Five months later, Boeing's 787 Dreamliner is once again aloft.

United Flight 1 took off from Houston Monday morning en route to Chicago. It marked the first flight of Boeing's next-generation airliner since the entire worldwide fleet of Dreamliners was grounded by the U.S. Federal Aviation Administration in January in the wake of multiple on-board fires.

The fires were found to be related to the plane's batteries, and in the months since then, Boeing and its suppliers have worked to correct the problems. Last month, the FAA approved Boeing's proposed fix to the battery issues, which included a new charging system and a new enclosure, and the aviation giant began installation on planes around the world.
